The Chapter 7 Chronometer Summer Edition 2025 by BA111OD captures the season with bold design and a carefree spirit. Returning as a capsule collection after a successful spring debut, this chronometer-certified watch is available in three radiant colors: fuchsia, turquoise, and yellow. Each model features a 40 mm black PVD stainless steel case, with water resistance up to 100 meters. The vibrant dial shades are complemented by interchangeable rubber straps in black and matching colors, making it an ideal companion for both outdoor adventures and city escapades.
Beyond its colorful exterior, the Chapter 7 Summer Edition houses a Swiss chronometer-certified movement, verified by the Geneva-based Timelab Observatory. This prestigious certification ensures high accuracy within a tolerance of -4 to +6 seconds per day. Each movement is fine-tuned to withstand a range of environmental conditions, including temperature shifts, shocks, and magnetic fields.
Rooted in Neuchâtel, BA111OD draws inspiration from the natural beauty and clarity of its surroundings. The Summer Edition reflects this harmony through the contrast of luminous dials and a deep black case. The refined faceted bezel and sunray dial offer a play of light that enhances the watch’s vibrant personality. With its unisex proportions, distinct off-center crown, and modern strap options, this timepiece is designed to elevate summer moments with both flair and functionality.
